along the side below the lateral line. Pectorals, ventrals, ancT 

 middle of caudal fin very slightly darker than the rest of the 

 fins. 



Described from three specimens, 287-300 mm. long; the 

 specimen figured is 300 mm. in length, and is selected as the 

 type. It is deposited in the South Australian Museum. A 

 series of thirty-six specimens, 227-560 mm. in length, exhibits 

 some variation in the length of the eye and the breadth of the 

 interorbital space; the former is 45 in the head in small 

 examples and 5*9 in the largest specimen; the interorbital 

 space is much broader in older specimens than in younger ones, 

 varying from 2'7-l*3 in the orbital length. 



This species was discovered by our friend, the late Harald 

 C. Dannevig, who obtained it in considerable quantity in 

 deep water in the Great Australian Bight, and considered it 

 would later become an important addition to the fish supply 

 of the Southern States. 



r. coTi'itua is very closely allied to P. macrodon, Ogilby, 

 but is readily distinguished by its much shorter and thicker 

 gill-rakers (plate xii., figs. 3 and 4) ; it usually has a narrower 

 interorbital space and its fins are lighter in colour, while a less 

 striking difference lies in the sculpture of the preopercular 

 bone, portion of which is generally exposed and radially^ 

 carinate in P. conaHis, and smooth and covered by skin in 

 P. macrodon. P. conatiis is possibly identical with either 

 P. grandis, Castelnau, or P. speculator, Klunzinger, but the 

 descriptions of both these species lack all reference to several 

 structures characteristic of our species ; further, both were 

 obtained from shallower water in the neighbourhood of Port 

 Phillip, whereas we have no record of P . connfns except from 

 deep water in the Great x\ustralian Bight.
